Magento Code Reviewer

This is a strict Magento 2 code reviewer that enforces PSR-12, Adobe Commerce standards, and type safety. It catches the usual suspects like missing strict type declarations, weak comparisons, and poor dependency injection, plus Magento-specific issues around observers, plugins, and service contracts. The review covers security (SQL injection, XSS, ACL), performance (N+1 queries, cache usage), and architecture patterns. What's useful here is the opinionated stance on minimal comments and constructor property promotion with readonly, which aligns with modern PHP practices. Use it before commits or during pull requests when you need eyes on compliance and don't want to argue about coding standards.
